The ordinate of a point is the signed measure of its projection on the secondary axis, whose absolute value is the distance between the projection and the origin of the axis, and whose sign is given by the location on the projection relative to the origin (before: negative after: positive). The abscissa of a point is the signed measure of its projection on the primary axis, whose absolute value is the distance between the projection and the origin of the axis, and whose sign is given by the location on the projection relative to the origin (before: negative after: positive). Abscissa x-coordinate 5 Ordinate y-coordinate 5 Coordinates (5, 5) Ex 3. The distance of a point from x-axis scaled. The abscissa and ordinate together are called the rectan- gular or Cartesian coordinates of the point (see Figure 7.2). Abscissa x-coordinate 5 Ordinate y-coordinate 2 Coordinates ( 5, 2) Ex 3.2, 2 See the given figure, and write the following: (ii) The coordinates of C. The distance of a point from the y-axis, scaled with the x-axis, is called abscissa or x coordinate of the point. ə/ plural abscissae or abscissas) and the ordinate are respectively the first and second coordinate of a point in a Cartesian coordinate system: abscissa ≡ x Ex 3.2, 2 See the given figure, and write the following: The coordinates of B. In mathematics, the abscissa ( / æ b ˈ s ɪ s. The distance of a point from the x-axis scaled with the y-axis is called the ordinate or y coordinate of the point.įor example, if (x, y) is an ordered pair in the Cartesian plane, then the first coordinate in the plane (x) is called the abscissa and the second coordinate (y) is the ordinate. Don’t forget that the first point you get will always be on the X portion of the graph, and the second number will always be the Y. For the point -1.5,-2.5, -1.5 is the abscissa and -2.5 is the ordinate. If x and y are abscissa and ordinate respectively, then the location of the point P in the Cartesian plane is expressed by the ordered pair (x, y). Following up, the point (0,0), 0 is the abscissa and the ordinate. The distance of a point from the y-axis, scaled with the x-axis, is called the abscissa or x coordinate of the point. The coordinates are written in the brackets (), where abscissa is written in the first position and then ordinate in the second position, separated by a comma. (denoting the part of a line between a point on it and the point where it meets an ordinate): from modern Latin abscissa (linea) ‘cut-off (line)’, feminine past participle of abscindere, from ab- ‘off’ + scindere ‘to cut’. The first value in each of these signed ordered pairs is the abscissa of the corresponding point, and the second value is its ordinate. the coordinate that gives the distance along the horizontal axis ( the one along the bottom) compare ordinate Word Origin early 17th cent. Horizontal and vertical axes/coordinate numbers of a 2D coordinate system or graph Illustration of a Cartesian coordinate plane, showing the absolute values (unsigned dotted line lengths) of the coordinates of the points (2, 3), (0, 0), (–3, 1), and (–1.5, –2.5).
